This 'invention relates "to iniprovements in tobacco pipes, and has for its object to provide a tobaccopipe having novel and improved means for desirably cooling the smoke-on its passage from the bowl to the stem for condensing and trapping `moisture and impurities to permit of their-'ready-removal and tov prevent passage of impurities generated in the compositionof the tobacco intothe stem, and for facilitating and rendering easier the cleaning of the pipe for removal of all deposits when required. Y

The invention consists of the features of construction, combination and arrangement of parts, hereinafter fully described and claimed, reference being had to the accompanying drawing, in Which:-

Fig. 1 is a top plan view of one form of tobacco rpipe embodying my invention.

Fig. 2 is a vertical longitudinal section through the pipe shown in Fig. 1.

Fig. 3 is a view similar to Fig.` 1 of a tobacco pipe embodying a modified form of my invention.

Fig. 4 is a vertical longitudinal section through the same.

Fig. 5 is a section on the line 5-5 of Fig. 4.

Referring now more particularly to Figs. 1 and 2 of the drawing, I designates a tobacco pipe having a bowl 2 and a stem 3, the bowl 2 being provided at its rear side with an extension 4 which is preferably formed integral with the bowl.

The bowl 2 is provided at its base with a smoke outlet passage 5, and the stem 3 is provided in its upper rear portion with a smoke outlet passage 5 arranged above the level of the passage 5. The passage 6 communicates with a bore 'l formed in the extension 4 and which is designed to receive the reduced end 8 of the stem 3, which is removably fitted therein.V

The passages 5 and 6 communicate with a combined cooling and trap chamber 9 formed vertically in the extension 4, which chamber opens at its upper end through the top of the extension 4 and is provided with a lower end portion or extension I0 of reduced diameter below the level of the passage 5 and which opens through the bottom of the extension 4.

The chamber 9 and its extension I0 are adapted to receive a cooling pipe or tube` II removably fitted therein. The lower end of this tube is formed to snugly fit the extension Il) ofthe passage 9, while that portion of the tube which fits within the passage 9 is of less diameter than said passage, thus forming therearound between it and the walls of the passage 9 an annular space through lwhich the .passages 5 and 6 are in normal communication with each other. AThe tube I I maybe made of metal or other suitable strong and durable material and is provided at its'upper end with a iiange I2 to limit its downward fmovement and to rest upon the upper surface of the-'extension 4 and close the upper end of the passage 9. A 'cleaning passage |3 is pro-A vided i-n the-rear of "the extension I in axial alinement with the passage 5. This passage I3 is normally closed by the tube I I when the latter is tted in position. Upon the removal of the tube II the passage I3 is in open communication with the passage 9 and passage 5, so that a suitable cleaning tool may be inserted through the passage I3 for the purpose of cleaning out the passage 5 in a ready and convenient manner.

The function of the tube II is to provide a cooling and condensing element located in the line of ow of the smoke between the bowl and the stem for the purpose of cooling the smoke to a desirable degree before it enters the stem, the tube also serving to condense any moisture flowing with the smoke and to cause its deposit in the chamber 9. By this means any moisture, oil or tobacco, nicotine or like substances are trapped and collected in the chamber 9 for removal when occasion requires, and such impurities are prevented from passing with the smoke into the stem of the pipe. The cooling eiiiciency of the tube or pipe I I is facilitated and increased through the fact that this tube is normally open throughout its length so that, through the heat collected by the tube from the smoke on its passage, an upward circulation of cool air will be induced through the tube, thus keeping it at all times comparatively cool and in proper condition for a condensing action.

A tobacco pipe embodying my invention thus provides means for cooling the smoke to a desirable degree and entrapping and collecting moisture and impurities and preventing the same from passing to the mouth of the smoker. By simply removing the tube Il the chamber 9 will be exposed and the passage I3 opened in line with passage 5 so that by means of a suitable tool or cleaner the parts of the pipe may be quickly and conveniently cleaned for removal of the deposited impurities. It will be understood also that any'saliva entering the passage G from the stem will be collected in the chamber 9 and prevented from flowing back into `the stem, the advantages of which will be apparent.

In the form of my invention shown in Figs. 3, 4 and 5 the general construction of the pipe Ia is the same as that previously described and shown in Figs. 1 and 2, corresponding parts being designated by like reference characters. The pipe structure Ia diiers, however, from the pipe structure I in that the cooling and trap chamber 9a is horizontal instead of vertical and extends transversely through and from side to side of the bore extension 4. The cooling and condensing tube II a in the pipe structure I a is also of dierent type from the tube II, the same comprising a ring or annular body tted in the passage 9a. 'I'he ring is channeled or corrugated, as shown at I4, to provide annular passages between it and the walls of the chamber 9, which passages are closed at their sides but communicate at the base of the tube with the passage 5, the passage 9 having at its point of juncture with the passage 5 an enlargement I5 for this purpose. The tube I Ia performs the same function as the tube I I shown in Figs. 1 and 2 and is open from end to end to provide an internal passage for the flow of cooling air therethrough. This tube is removable from the passage 9a to allow and facilitate cleaning of the tube, the passage 9a and the passage 5 for the removal of impurities. In both forms of constructiony of my invention the passage 6 is readily cleansed for the removal of any impurities which may be deposited therein upon detachment of the stem 3, as will be readily understood.

From the foregoing description, taken in connection with the accompanying drawing, the construction and mode of operation of my improved pipe structures will be readily understood and the advantages thereof appreciated by tobacco users and others versed in the art without a further and extended description. While the structures shown are preferred, it will, of course, be understood that changes in the form, proportions and detailed features of construction may be made within the scope of the appended clairm, without departing from the spirit or sacricing any of the advantages of the invention.

What I claim is:-

A tobacco pipe having a bowl and a stem, the bowl and stem being provided with smoke passages and the bowl having a smoke cooling and impurities collection chamber extending therethrough at right angles to and intersecting the passages, and the bowl further having a clean out passage in line with the smoke passage therein, and a. cooling and condensing tube removably tted in the chamber so as to normally close the ends of the chamber and clean out passage while providing a circulation space in the chamber between the passages.
